In simple style drawings, like Comics and traditional cel animation, curved strokes are relatively important. Of course, the shape of the curve is the most important. However, subtle changes of curve width cannot be ignored. We propose a powerful method allowing subtle width changes to be applied to general 2D curve data. The algorithm is based on curvature information of the input curve, and keeps carefully the impression of the original curvature. The resulting image expresses a pen-and-ink drawing style.
